9
10 - added a new loop to callisto to support the correct extraction of
11 the pedestal and pedestal rms through the signal extractor

253 replace MReadMarsFile as soon as it is finished.

256 and how they can be read from the root file in the correct order
257 of time (readrep.C)

363 - added a new status display which can show the present status
364 of histograms while an eventloop is running (MStatusDisplay,
365 an example can be found at status.C)
366
367 - reorganized directories:
368 classes describing the image --> mimage

400 missing a single NN)
401
402 - Fixed a bug in the table describing the Next Neighbours of the
403 CT1 camera (a pixel 127 doesn't exist and the pixel 126 didn't
404 have any neighbour)
405
406 - changed trigrate.C: now it calculates the pure NSB triggers from
407 a camera file (generated with no showers), so there is no need
408 to introduce them by hand in the BgR array (for more details
409 please ask Abelardo)

460 its setup to a file. This information can be read and from
461 it you can (re)create a Macro. See MEvtLoop::Read, MEvtLoop::Write
462 and MEvtLoop::MakeMacro. If you find something not working, please
463 report - this stuff is still in a beta phase.
464
465 - MBlindPixelCalc set all Ceta-Tauri pixels to unused not only for the
466 file having crab starfield, but also for all following files - fixed
467
468 - MTaskList::PrintStatistics can now be instructud to print also the
469 title, too: use PrintStatistics(0, kTRUE)

492
493 *** Version 0.7 (2002/04/30)
494
495 - added a bugfix to MCerPhotCalc. In older camera versions (<=40)
496 the pedestal mean value was saved incorrectly. For files from
497 this versions we substract 0.5 from the pedestal mean.
498 WARNING: This may effect your results, so don't wonder...
499
500 - First implementation of an algorithm using only triggered events
501 for the collection area calculation
502
503 - Ascii Output can now also be used for parameter containers which
504 doesn't overload MParCointainer::AsciiWrite
505
506 - The Ascii Output is now also capable of writing single data members
507 of one container
508
509 - You are now able to change the order of the values written to the
510 ascii file
511
512 - You can now specify a conversion factor for each data member written
513 to an ascii file. This may be usefull to change the units of the
514 data member (eg. degrees instead of millimeters in case of the
515 hillas parameters)
516
517 - Replaced old MHillas by a new structure which allows you to extend
518 the parameters stored in MHillas very easily:
519 see MHillas and MHillasExt
520
521 - Added classes to handle source dependancy of image parameters:
522 see MHillasSrc
523
524 - Added container (MBinning) to have a standard input for the binning

528 - Changed Hillas histograms from mm to deg
529
530 - Added the flexible binning to the hillas histograms
531

538 MFDataMember filter("MHillas.fWidth", '<', 0.5);
539
540 - Added a generalized Filter parser for more difficult filter rules

549 data members in either a one-, two- or three-dimensional histogram, eg:
550 MH3 mh3("MHillas.fWidth", "MHillas.fLength");
551
552 - Added:
553 * calculation of <Theta> as a function of Theta (MHThetabarTheta)
554 * calculation of <Theta> as a function of time (MHThetabarTime)
555 they are needed in the flux calculation in
556 order to select for a given bin in Theta (or time) the appropriate
557 effective collection area, which is assumed to be given as a function
558 of Theta and the true energy
559
560 - Added calculation of the migration matrix in the energy
561 (MHMcEnergyMigration):
562 the migration matrix describes the migration from the true (E_true)
563 to the estimated energy (E_est); it is needed to determine the
564 distribution of E_true from the measured distribution of E_est
565 by unfolding
566

591 - Introduced MMcRunHeaders which contains monte carlo run informations
592
593 - Added a 'Print'-Task (MPrint) which calls the Print function
594 of a parameter container for each event
595
596 - Removed MHtml (was replaced by THtml of root 3.02) in dohtml.C
597
598 - changes to be more efficient with root 3.02/06
599
600 - root 3.02/06 fixes:
601 + the memory leak when reading MRawEvtData
602 + loosing more time than necessary to update the progress bar
603
604 - MWriteAsciiFile is now capable of writing more than one container
605 in a line. For example: To be able to write Monte Carlo and
606 Hillas values (energy and alpha) in one line.
607
608
609
610 *** Version 0.5 (2001/11/06)
611
612 - Added new GUI functionality (Analysis)
613
614 - Added a camera display to be able to display events in the camera
615 together with the calculated hillas ellipse
616
617 - Added a 'Clone'-Task (MClone) which can clone a parameter container
618 object at any state of the analysis, so that the output are several
619 states
620
621 - Fixed a bug in the collection area error calculation
622 (Thanks to Ciro and Abelardo)
623
624 - Fixed a bug which causes merpp to crash in some environments
625
626 - Implemented auto enabling scheme for Branches to speed up reading
627 a lot (see MReadTree and MTask)
628
629 - Fixed a bug in the Histogram classes which caused histograms to
630 be written to a file by MWriteRootFile without request
631
632 - changed the object I/O from the old stylish root I/O to the new
633 'auto evolution scheme' This was done only for classes which are not
634 yet used in Monte Carlo files, so that these files are still readable.
635
636 - Added support for a progress bar in MEvtLoop and MReadTree
637 (see the Analysis Window in Mars for an example)
638
639 - Fixed a bug in the package creation which disturbed the conversion
640 between a mars version unpacked from a tar file and the repository.
641
642 - Changed the code to writer merpped (converted into root format)
643 raw files, to get faster (around 10%)
644
645
646
647 *** Version 0.4 (2001/09/20)
648
649 - This release is made to compile on a root version >= 3.00
650
651 - Fixed a bug which causes MReadTree to read the first file only
652
653 - Added a task to compute the trigger rate (MMcTriggerRateCalc)
654
655 - Added a task to write a container to an Ascii file (MWriteAsciiFile)
656
657 - Added a task to write several container to a root file (MWriteRootFile)
658
659 - Added calculation of the Enegry Threshold (MMcThresholdCalc)
660
661 - Added calculation of the collection area (MMcCollectionAreaCalc)
662
663 - fixed some bugs in the Hillas calculation
664
665 - added filters to be able to control the task execution dependent on
666 a parameter (for example: the number of level 1 triggers in a MC-file)
667
668
669
670 *** Version 0.3 (2001/04/23)
671
672 - Many demo macros added

675
676 - Hillas Calculation added
677
678 - Standard image cleaning available
679
680 - MReadTree is now able to handle more than one file
681 (Remark: of the same structure)
682
683 - Now we are able to display events in a first version of the
684 Camera event display. To do this we must run the macro
685 "macros/readCT1.C" to read data from CT1.
686
